Registers a remote MCP server with VS Code so Copilot Chat (Agent mode) can call its tools. Users do not need to edit mcp.json — installing this extension is enough.

Default server

https://mcp.uat.pinelabs.com/mcp

Override it in Settings → Extensions → Utility MCP → Server URL.

Develop

npm install
npm run build
# Press F5 in VS Code to launch an Extension Development Host.

In the dev host, open Chat → switch to Agent mode → click the Tools icon — your server's tools will appear under "Utility MCP".

Package & install locally

npm run package        # produces utility-mcp-vscode-x.y.z.vsix
code --install-extension utility-mcp-vscode-0.0.1.vsix

Publish to the Marketplace

1. Create a publisher: https://marketplace.visualstudio.com/manage
2. Update publisher in package.json.
3. npx vsce login <publisher> then npm run package && npx vsce publish.

How it works

The extension contributes an mcpServerDefinitionProviders contribution point and registers a McpHttpServerDefinition pointing at the Streamable-HTTP MCP endpoint. VS Code starts/stops the server automatically and surfaces its tools to Copilot Chat.
